Specific embodiment
The present invention is described in detail with reference to the accompanying drawings and detailed description.
A kind of flexible printing machine gloss oil overprinting method, is carried out using gloss oil Chromatic Printing Control System, as shown in figure 1, gloss oil chromatography system
System structure be：Including roller servo-driver 3, model 2094-BM03-M of roller servo-driver 3, roller servo-drive
It is provided with color mark sensor 5, roller servo-driver 3 is connected to controller 1, roller servo-drive by switch 4 before device 3
Device 3 is connected with roller motor 2 and provides power for it, switch 4 is also associated with man machine interface 6, facilitates operator to check phase
Answer parameter；
Specifically implement according to following steps：
Step 1, the color code block that setting a cycle occurs in printing, when color mark sensor 5 detects this color code block
When, roller servo-driver 3 writes down the current location of roller servo-driver 3 when colour code is detected, and this signal is passed through to exchange
Machine 4 reaches controller 1, and controller 1 is using it as reference value M1, and an angular range is set on the position of this benchmark, should
Angular range is " door "；
Step 2, when in described step 1 door determine after, whenever roller servo-driver 3 turns to the position of benchmark again
Postpone, color mark sensor 5 detects the position of colour code, controller 1 records the position of roller servo-driver 3 again, be designated as measuring
Value M2, and this position and original reference position are compared, by reference value M1With measured value M2Deviation be designated as Δ M；
Step 3, Δ M is carried out with an amplitude limit, that is, Δ M span is -3≤Δ M≤3, the gate value model as in step 1
Enclose, as Δ M>When 3, value is 3 to Δ M all the time, as Δ M<Value is -3 all the time for -3, Δ M.
Step 4, Δ M is filtered：By the Δ M value that in described step 3, continuous 5 times collect, remove maximum and
Then remaining 3 Δ M values are sought arithmetic average, are obtained filtered Δ M value by little value；
Step 5, judge the filtering of described step 4 after the scope of Δ M that obtains, iterative double clipping is carried out to Δ M：If -0.1<
ΔM<0.1, Proportional coefficient K will be multiplied by by Δ M1, K within the range1Value is 0.03, finally gives M=Δ M*K1；

For 0.18, finally give M=Δ M*K2；
Step 6, when in described step 5 M value determine after, if M>0, controller 1 receives M>0 signal, controller 1 is controlled
Plate-making roller servo-driver 3 rotates forward, and meanwhile the distance of adjustment roller motor 2 is M, and the speed of adjustment roller motor 2 is
20m/s, deceleration are 20m/s2；If M<0, controller 1 receives M<0 signal, controller 1 can control roller servo-drive
Device 3 inverts, and meanwhile the distance of adjustment roller motor 2 is M, and the speed of adjustment roller motor 2 is 20m/s, acceleration is
20m/s2；
Δ M is filtered process principle be：If each width picture is all adjusted, it is likely to result in roller motor
2 frequent concussion, is likely to result in beating of chromatography, following adjustment chromatography precision is found through experiments preferably, i.e. every five width
Picture carries out single compensation, only carries out position compensation when deviation delta M is smaller simultaneously, and the gain coefficient of position compensation than
Less, when deviation delta M than larger when not only position compensation to be carried out, and velocity compensation to be carried out, the increasing of position compensation simultaneously
Beneficial coefficient is than larger.
Flexible printing machine gloss oil overprinting method, greatly reduces the scrap piece loss during gloss oil chromatography, reduces equipment cost,
Efficiency and automaticity improve simultaneously, and multiple axes system contributes to shortening engineering and set-up time, and Programmable Multi-Axis Controller will
The discrete control of high speed and motor control are integrated in identical platform, strengthen control, reduce programming difficulty and improve can
By property.
